In this paper, we address the problem of person re-identification, which refers to associating the persons captured from different cameras. We propose a simple yet effective human part-aligned representation for handling the body part misalignment problem. Our approach decomposes the human body into regions (parts) which are discriminative for person matching, accordingly computes the representations...
Taking digital photographs as a form of documentation while conducting field work is common practice. There is a wealth of digital photographs collected by foresters who are interested in tree architecture. These high-resolution photographs are two-dimensional representations of the tree structure. However, it is possible to exploit tools such as GIS (e.g., ESRI ArcGIS) and three-dimensional modelling...
Self-occlusion is a challenging problem existing in human pose estimation. In this paper we exploit a new cue to solve this problem: the torso orientation. We describe a technique to automatically detect self-occlusion in training set without visibility label. Given this prior information, we are able to jointly learn an occlusion-aware model to capture the pattern of self-occluded body parts. We...
The subject of this paper is monitoring of thermal effects on human head from mobile phones. In this paper temperature distribution and SAR at surface of human head close to source of electromagnetic radiation are shown. Results of simulation were compared with experimental results obtained with thermal imaging camera.
Physical models for biological molecules have been used since the 50s to represent their structures at a macroscopic scale. Nowadays, advanced modular non-rigid models (such as the Peppytide tangible interface) successfully approximate the bonding rotational energies and enable realistic folding of small proteins. Such tangible interfaces are also an interesting way to interact with 3D virtual objects...
Most sophisticated mammals, in particular primates, interact with the world to acquire knowledge and skills later exploitable to obtain biologically relevant resources. These interactions are driven by intrinsic motivations. Recent research on brain is revealing the system of neural structures, pivoting on superior colliculus, underlying trial-and-error learning processes guided by movement-detection,...
Models are used in control domains for early validation of system properties, using simulation or formal verification, and for the automatic generation of a software implementation. We propose an approach in which a functional model of the controls is matched to a model of the execution platform through an intermediate mapping model, that represents the software tasks and communication messages. The...
Three-dimensional models of fingerprints obtained from contactless acquisitions have the advantages of reducing the distortion present in traditional contact-based samples and the effects of dirt on the finger and the sensor surface. Moreover, they permit to use a greater area for the biometric recognition.
We propose a model-based approach for human body pose recognition from a single-view depth camera. The proposed algorithm applies an articulated cylinder model to detect human pose and track them based on a particle filter without numerous training data or heuristic detectors. To reduce high degrees of freedom, we adopt a hierarchical method that detects torso and limbs successively. Moreover, we...
Iris recognition has been proven to be an accurate and reliable biometric. However, the recognition of non-ideal iris images such as off angle images is still an unsolved problem. We propose a new biometric targeted eye model and a method to reconstruct the off-axis eye to its frontal view allowing for recognition using existing methods and algorithms. This allows for existing enterprise level algorithms...
Recent advances in technologies for capturing video data have opened a vast amount of new application areas. Among them, the incorporation of Time-of-Flight (ToF) cameras on Ambient Intelligence (AmI) environments. Although the performance of tracking algorithms have quickly improved, symbolic models used to represent the resulting knowledge have not yet been adapted for smart environments. This paper...
A computational saliency model utilizing bio-inspired features for spatiotemporal saliency is presented in this paper. We first propose distributed opponent oriented energy for compact local dynamic texture description motivated by Human Vision System. Then, we integrate the derived motion characterization and a revised self-resemblance saliency framework. High effectiveness and efficiency of the...
The human gait is one of the most important movements for the development of the human being life. It represents a sequence of synchronized movements of the joints and muscles activations of the lower limbs. The knowledge of how those movements are performed, taking into account the biomechanical foundations and the physiology of the elements involved, is very important in order to be able to identify...
Since the 1980's computer aided engineering (CAE) and simulation (CAS) methods are widely used in the car development process. First the focus was set on crash simulation and car body design. Since a few years due to the rapidly increasing complexity of new electronic systems these techniques are applied in the development and test processes of advanced driving assistance systems (ADAS). There are...
The performance of an automatic hand geometry authentication system relies heavily on the quality of the captured hand images. Factors related to the acquisition device (e.g. dirty scanner surface) or the user-sensor interaction process (e.g. hand positioning) can degrade the quality of the acquired sample. Therefore, upon capture of a hand sample it is important to assess its validity. In this paper,...
For the purpose of medical education, our research team is creating LINDSAY, a 3-dimensional, interactive computer model of male and female anatomy and physiology. As part of the LINDSAY—Virtual Human project, we have developed a component-based computational framework that allows the utilization of various formal representations, computation engines and visualization technologies within a single...
This paper presents a new robust digital image stabilization system, which involves a practical motion model based on a feature-histogram. The feature-histogram is used for adaptive selection of feasible motion estimation regions. By estimating the representative motion vector in the optimally selected region, the proposed algorithm can robustly remove undesired camera vibration regardless of object's...
This paper explores art, Artificial Life and the creation of new modes of realism. A brief survey charting significant Artificial Life artworks using aesthetic selection contextualizes the current status of realism in Artificial Life. Drawing on dasiamedia ecologypsila the paper examines the relationship between realism, codes of representation and what we see as real and dasiatrue to lifepsila. These...

Despite leaps in motion capture technology, the dichotomy between unencumbered vision-based motion recovery and the prevailing marker-assisted motion capture solution remains largely pertinent. This paper bridges the gap by introducing an attachment-free, full-body motion capture technique that employs multiple high-speed cameras and a customized bodysuit. The flexible bodysuit allows free movements...
